How would I create I rule for HTTPS client redirect

What version are you on? Before 11.4 you could use an HTTP Class (Local Traffic ›› Profiles : Protocol : HTTP Class). If you're on 11.4 you can use a Local Traffic Policy.

You could also use an iRule:

when HTTP_REQUEST {

    if { [string tolower [HTTP::path]] starts_with "/webapp/rest/public/redirect/android" } {

        HTTP::respond 302 Location "https://play.google.com/store/apps/details?id=org.penfed.mobile.banking"

    }

}

Note that I used "starts_with". This may or may not work in your case (depending an whether any other paths start with "/webapp/rest/public/redirect/android"). However, "starts_with" does get around other issues that often plague redirects (e.g. trailing slashes, inclusion of default file names (like index.html)).
